With the disclaimer that I am but a teacher (so take whatever I am going to say with a giant grain of salt), I would say that the answer is not to try and replicate the iOS / Android smartphone ecosystem in its entirety, but to push for a new equilibrium. It could be AI, it could be some new technological platform I have not heard of. In short, don’t try to compete with smartphones but instead look towards moving beyond the smartphone.
Remember that Google makes no money off android. Their business model is ultimately in selling ads, so you have to attack them where their money is.
Maybe still easier said than done, which is why I am sitting here after dinner replying to you and not pitching investment ideas to venture capitalists.
